  摘要：The robust exponential stabilization is addressed for uncertain delay reaction-diffusion systems via sliding mode boundary control (SMBC). First, a novel integral sliding mode surface (SMS) is proposed, on which system states slide to the equilibrium with an exponential convergence rate. Furthermore, the sliding mode boundary controller (SMBCr) is designed to steer system states to the SMS in finite time. A criterion is established for robust exponential stability by utilizing the Lyapunov-Kra...
• Robust, Positive, and Exact Model Reduction via Monotone Matrices AI翻译

  摘要：This work focuses on the problem of exact model reduction of positive linear systems, by leveraging minimal realization theory. While determining the existence of a positive reachable realization remains in general an open problem, we are able to fully characterize the cases in which the new model is obtained with nonnegative reduction matrices, and hence positivity of the reduced model is robust with respect to small perturbations of the original system. The characterization is obtained by sp...

  摘要：This article studies the feedback optimization problem for nonlinear systems. In particular, we assume that the controlled plant admits a global asymptotic stable equilibrium corresponding to each fixed reference input and consider a modified gradient-flow optimizer augmented with a nonlinear perturbation function. With the output map of the controlled plant satisfying a linear growth condition, this article proves the existence of a perturbation function such that the resulting feedback optim...
• Adaptive Threshold Selection for Set Membership State Estimation With Quantized Measurements AI翻译

  摘要：State estimation for discrete-time linear systems with uniformly quantized measurements is addressed. By exploiting the set-theoretic nature of the information provided by the quantizer, the problem is cast in the set membership estimation setting. Assuming the possibility of suitably tuning the quantizer range and resolution, the optimal design of adaptive quantizers is formulated in terms of the minimization of the radius of information associated to the state estimation problem. The optimal...
• MPC for Linear Systems With Concave Inequality Constraints and Convexification Loss Analysis AI翻译
  作者：Deng, Yunshan; Xia, Yuanqing; Sun, Zhongqi; Li, Chang; Hu, Rui

  摘要：In this article, we propose a model predictive control (MPC) algorithm using sequential convex programming (SCP) to address concave inequality constraints. Based on traditional SCP, we introduce two methods to improve the solution quality and reduce the cost when SCP is stopped early at each time step. First, we analyze multiple explicit representations of a single constraint and propose a method to reduce convexification loss without solving additional nested dual problems. Second, we map the...
• Achieving Local Consensus Over Compact Submanifolds AI翻译

  摘要：Decentralized optimization often relies on achieving consensus among disparate agents. This article addresses the consensus problem in decentralized networks, focusing on the challenges posed by a nonconvex compact submanifold constraint. We identify conditions on network topology that facilitate local linear convergence to global consensus, where the achieved linear rate matches that of the Euclidean setting. Central to our analysis are the convex-like properties, specifically proximal smooth...

  摘要：For stabilizing stop-and-go oscillations in traffic flow by actuating a variable speed limit (VSL) at a downstream boundary of a freeway segment, we introduce event-triggered partial differential equation (PDE) backstepping designs employing the recent concept of performance-barrier event-triggered control (P-ETC). Our design is for linearized hyperbolic Aw-Rascle-Zhang (ARZ) PDEs governing traffic velocity and density. Compared to continuous feedback, ETC provides a piecewise-constant VSL com...

  摘要：This article presents a deep learning-based model predictive control (MPC) algorithm for control affine nonlinear discrete-time systems with matched and bounded state-dependent uncertainties of unknown structure. Since the structure of uncertainties is not known, a deep neural network is employed to approximate them. In order to avoid any unwanted behavior during the learning phase, a tube-based nonlinear model predictive controller is employed, which ensures satisfaction of constraints and in...
• Distributed Proximal-Correction Algorithm for the Sum of Maximal Monotone Operators AI翻译

  作者单位：Dalian University of Technology; Guangxi University; Northeastern University - China
  摘要：This article focuses on a class of inclusion problems of maximal monotone operators over directed multiagent networks, where each agent is characterized by a splittable local operator. By integrating the ideas from correction, inexact proximal methods, and push-sum protocol, we proposed a distributed proximal-correction algorithm (referred to as DPCA-& varepsilon;(i)(k)) to solve this inclusion problem of operators, where -& varepsilon;(i)(k) is an agent predetermined accuracy for approximatel...
• Value of Information in Games With Multiple Strategic Information Providers AI翻译

  摘要：In the classical communication setting multiple senders having access to the same source of information and transmitting it over channel(s) to a receiver in general leads to a decrease in estimation error at the receiver as compared with the single sender case. However, if the objectives of the information providers are different from that of the estimator, this might result in interesting strategic interactions and outcomes. In this work, we consider a hierarchical signaling game between mult...
